How should ordinary people deal with the adjustment or cancellation of nucleic acid testing and the gradual liberalization of prevention and control? First of all, we need to correctly understand the &”;gradual liberalization of prevention and control&”;. 1. The process of our struggle against the virus is also a process of constantly gaining anti-epidemic advantages and gradually opening up. As early as half a year ago, the academician said this: Under the current situation of our country, &”;complete opening is not applicable, and dynamic clearing is desirable, but a policy of gradual opening is needed.&”; Academician 2. &”;Optimizing twenty prevention and control measures&”; is a key step in the process of &”;dynamically clearing&”; the epidemic. &”;Twenty measures to optimize prevention and control&”; has aroused widespread repercussions. As far as the reasons are concerned, compared with the previous epidemic prevention policies, the adjustment of this policy is relatively large. In any case, we should realize that every step we take shows the expansion of our anti-epidemic advantages and that we are gradually returning to normal life. Optimizing 20 prevention and control measures is related to the scientific nature of nucleic acid detection. Secondly, we need to understand that only by taking all protective measures can we stay away from the virus. 1. Although the virus has weakened its toxicity after continuous mutation, its spread speed is faster and it will bring greater harm to the old and weak people. 2. After being infected by the virus, our body and mind will be greatly affected, for example, we need isolation treatment and we need to adjust our psychology for a long time. 3. The best way to defeat the enemy without fighting is to stay away from the virus. How to stay away? Wear a mask when traveling, keep a social distance and pay attention to personal hygiene. Wearing a mask is the basic epidemic prevention measure for us to protect ourselves. Thirdly, we should pay attention to the enhancement of our immunity. 1. Immunity is the best doctor. The confrontation between human body and virus is also the confrontation between human immunity and virus toxicity. With strong immunity, we can stay away from the virus, or even if we are infected by the virus, we will not be greatly hurt. 2. Those who should be vaccinated must be vaccinated. Vaccination is an important way to prevent virus infection or weaken virus invasion. If vaccination has not been completed, vaccination should be completed as soon as possible. In the future, the fourth dose (inactivated vaccine) may be inoculated, and we should all respond positively. Vaccination 3. Enhance immunity through good living habits. These good living habits, such as the habit of exercising, reasonable and comprehensive diet nutrition, combining work and rest, ensuring sleep and maintaining a good mental state, etc. As far as physical exercise is concerned, aerobic exercise can enhance cardiopulmonary function, strength training can strengthen muscles and bones, the functions of different organs have been strengthened, physical fitness has been improved, and immunity has been enhanced. Exercise can enhance immunity. 4. For the old and weak, some drugs can be prepared appropriately. 1. The old and the weak should protect themselves. There are 267 million elderly people in our country, of whom about 200 million elderly people have one or more functional diseases. As an elderly person, we need to enhance our immunity from different aspects. It is necessary to prepare some medicine properly.Want. What medicines should I prepare? According to the recent notice of Chongqing Municipal Health and Health Commission, Chinese medicine can prepare Lianhua Qingwen Capsule, Huoxiang Zhengqi Liquid, Jizhi Syrup, etc. As for oral drugs, there are azvudine tablets, Monoupiva and Paxlovid which have been listed. However, western medicine should be used according to the doctor&;s advice, and Lianhua Qingwen capsule should be used.
